4/1/13 10:59 AM EDT

President Obama kicked off the 2013 Easter Egg roll with a few words about the weather, which started out foggy Monday before turning sunny.

"It was a little shaky this morning -- all of you did a great job sending messages upstairs and now we've got great weather," he said, before introducing "the star of the Obama family, my wife, the first lady, Michelle Obama."

The first lady welcomed guests to the South Lawn-- some 30,000 are expected throughout the day.

"We want you to have a great time," she said, and added later, "Kids, eat your vegetables."
